Improve caching when building gosuper

Browse Source 
It seems that the ARG ARCH causes a cache miss in the next RUN statement (for some reason our use of cache-from in the other stages of the build works better, but here it always causes a miss).
We move the ARG statement to later in the Dockerfile, just before actually using it. Hopefully this will improve caching for most supervisor builds.
